Figure 1: Increased Th1 and inflammatory cytokines in
premalignant lesion tissue compared to levels in normal or HNSCC
tissues. Normal oral tissues, premalignant lesions or HNSCC
tissues were homogenized and used to measure cytokine levels
using CBA. Plasma from these same patients was also analyzed for
cytokine levels by CBA. Cytokine levels in tissues were standardized
to levels of protein. Shown are means + SE from at least 10 patients
per group. *p<0.05; **p<0.01.
